IMPROVED APPARATUS FOR COOLING MALT LIQUORS.

Specification forming part of Letters Patent No. 50,293, dated October 3, 1865.

To di whom, it may concern:

Be it known that I, FRANCIS L. VVISSMANN, of the city of Philadelphia and State of Pennsylvania, have invented a new and' useful Improvement in Apparatus for Cooling Malt Liquors 5 and I do hereby declare the following to be a full and exact description of the same, reference being had to the accompanying drawings, and to the figures and letters ot' reference niarliedthereon.

My invention relates to that class ot' cooling apparat-us in which the liquor to be cooled is conducted over the outer surface of a series of horizontal pipes, these being alternately so connected at the ends as to form a continuous vertical coil or tier, through which flows the cooling` agent, (ice-water or cold spring-water.)

The object of my improvement is to increase the efficiency of such apparatus so that a given quantity ot'liquor may be cooled with a lesser numberI ot' pipes and by means of a smaller quantity of cooling liquid than with the same class ot' apparatus as heretofore constructed; and the nature of the improvement consists in the use ot' tubes ot' such peculiar t'orm as will give a much greater amount of cooling-surface in proportion to the area of section than could be obtained with the use of plain cylindrical pipes.;

Another feature of nl v improvements consists in providing a more perfect delivery and even distribution of the liquor over both sides ot' each pipe in its descent from one to the other.

Instead ot' the plain cylindrical tubes herctofore employed, I use tubes ot' a tlat or oval section, the sides of which are, moreover, corrugated,wherebythe cooling-surface is so much increased that an apparatus of a certain capacity will, when made on my improved plan, require but half the number of tubes that were heretofore necessary to effect the same object. With the use of fewer tubes their connectingpieces and end joints are likewise diminished in number, and thus the cost ot' the apparatus is very much reduced.

1n order that my said invention maybe fully understood, I will now proceed more particularly to describe the same.

On reference to the drawings making part of this specification, and in which similar letters allude to like parts in both views, Figure l is a side view of my improved cooling apparatus, and Fig. 2 a sectional end view of the same.

A A are the corrugated pipes, the Whole series (numbering six iu the drawings) being so connected by end pieces, B B, as to form a continuous channel for the cooling liquid. The pieces B B are provided with pivots or bearers G C, by means of which the whole train of pipes is suspended in a wooden frame consisting of two uprights, D D, and top crossA bars, E E, which latter pieces carry the V- shaped distributing-trough F. The uprights D D rest in the receiving-trough G, in which the cooler liquor, alter having flowed from the vessel F over the outer surface of the corrugated pipes, is collected, and from here conducted to the fermenting-vats or other vessels through the outlet H. The distributing-trough F is, at its lower edge, provided with a row ot' small holes, ff, through which the liquor iiows in smalljets and is distributed over the top surface otthe uppermost one of corrugated pipes A A. v

In order to insure a perfectly even distribution of the liquor over both sides of each succeeding pipe, I make use ot zigzagged or laterally-undulated distributing-strips ct e, at the bottom of each pipe, which strips, deviating from the center line to both sides ofthe same, produce the desired eft'ect, so that with their use any slghtdefect in the settingot'tbe pipes will have no injurious effect upon the working ot' the apparatus, while with the Ineans heretofore employed for this purpose (consisting in straight strips with toothed saw-shaped lower edge) the least inequality in the fitting of the tubes causes an unequal distribution of the liquor in its descent.

Having thus described the object and nature of my invention, I desire to be understood that I do not broadly claim as new a method ot' cooling liquors by liowiug the sante over the outer surface of pipes, arranged as herein set forth; but

What I claim as my invention, and desire to secure by Letters Patent, is

l. The described improvement in apparatus for cooling malt liquors, consisting in the use of the corrugated pipes A A, of a iiattened or oval section, and otherwise arranged as and for the purpose specified.

2. Thelaterally Zigzagged or undulated distributing-strips a a, whether used in connection with the described corrugated pipes or with any other form of tubes, as and for the purpose described.
